Abstract
A damping device for use in industrial machinery and tools comprising a housing ( 102, 602 ) and a flange member ( 104, 604 ) arranged in the housing, wherein at least portions of the flange member apart from the center thereof are composed of an elastic material and inclined with respect to the axial direction or the radial direction of the rotational axis and the flange member is so designed that the peripheral face thereof is brought into contact with the inner wall of the housing. This device can generate a damping force which may be drastically changed depending on the operating directions and thus permits stable damping. In the direct acting type one, the flange member ( 104 ) is tapered on the corresponding both faces towards the periphery thereof, it never requires the formation of any space for allowing any deformation on the largely deformed side, the device can thus be miniaturized in the axial direction and permits the reduction of the weight thereof and it can operate even in response to motions having a fine amplitude to thus show excellent damping characteristics. In the rotary type one, the flange member ( 604 ) comprises an engaging member capable of being engaged with a shaft body ( 603 ) and is provided with projected or convex portions ( 604 a) on its outer periphery. The projected portions are inclined towards the radial direction of the rotating shaft to thus efficiently show their excellent differential rotation-damping characteristics and the damping characteristics may arbitrarily be controlled. These damping devices can be used as dampers for suspensions of bicycles, rotary dampers applied to chairs and dampers for opening and closing doors.
Description
Technical field
The relevant damper device of the present invention, particularly relevant industry be with in the employed damper devices such as machine, produces damping force during differential between two members, can produce the damper device because of the significantly different damping force of its moving direction.Be particularly suitable for can be to linear reciprocation differential and rotate the differential damper device that carries out damping.
Background technique
As damper device, we know the so-called straight line moving type oil formula damper device that uses the wet goods flow resistance all the time, for example employed vibration damper such as automobile.There is following problem in this oily formula damper device.
(1) owing to pattern of wants stream in the casing, so complex structure, manufacture cost increases.
(2) fluid and constitute stream in to establish parts many, weight increases.
For this reason, as the problem that solves this oil formula damper device, simplified structure more, but the also damper device of weight reduction have proposed to use the motion (for example, with reference to the flat 11-511229 communique of special table) of the damper device of frictional force.
In the damper device that this announcement communique is recorded and narrated, shown in the Fig. 1 in the communique waits, for flange plate 23 as man made rubber plectane 22, only on the face of one side, put supporting plate as backing plate 26, by its multi-disc overlapping configuration, with the distortion of the flange plate that limits a direction (shrinkage direction among Fig. 1), and other direction (bearing of trend among Fig. 1) is a free deformation.Its result for the friction of cabinet wall face and flange plate 23 circumferential surfaces, will make the frictional force that produces because of direction separately produce difference.
There is following problem in the damper device that above-mentioned announcement communique is recorded and narrated.
(1) the friction generating mechanism of this technology depends on the crimping of cabinet wall face and flange plate 23 circumferential surfaces, and it is an easness of merely adjusting the flange plate distortion with supporting plate, produces the difference that causes because of moving direction for frictional force.Therefore, because the cabinet wall face when static and the crimp force maximum of flange plate 23 circumferential surfaces, so friction of rest is also bigger, when particularly adopting as tubular buffer (vibration damper), owing to be difficult in the sense of rotation rotation, installation property is not good.
(2) owing to be to adjust damping force, so, need the space of allowable strain in the large deformation side according to the distortion easness of flange plate 23.
(3) must use can bear the supporting plate that deformation load is made by stronger material.For this reason, use steel plate usually, when weight increases, axially be difficult to compactness.
(4) to-and-fro motion that is transfused to, during for the small amplitude in flange plate 23 deformation bands, on the direction of free deformation, if the words of the microvibration in the deformation band, do not produce frictional movement between the circumferential surface owing to cabinet wall face and flange plate 23 so, so do not produce damping force.In order in small amplitude, also to make it motion, need reduce friction of rest, so need make flange plate 23 miniaturizations reducing crimp force, but at this moment certainly the kinetic friction during large amplitude also diminish, so small amplitude and large amplitude are difficult to average out.
In addition, as other damper device, utilize the viscous oil formula damping due to rotation apparatus of the flow resistance of viscosity wet goods as everyone knows in addition.Though use in multiple field such as for example door closer, strut bearing portion, lid open-close mechanism etc., there is following problem in this oil formula damping due to rotation apparatus.
(1) owing to pattern of wants stream in the casing, thus complex structure, the manufacture cost height.
(2) fluid and constitute stream in to establish parts many, weight increases.
(3) because for using fluid to need fluid-tight sealing gasket, slipper seal pad etc., so need high dimensional accuracy, manufacture cost increases.
In order to solve the problem of this oil formula damping due to rotation apparatus, the motion (for example, opening the 2002-193012 communique with reference to the spy) of the rotation damper of the frictional force utilized is arranged.The rotation damper that the disclosure communique is recorded and narrated shown in record in the communique and accompanying drawing 1 etc., is the frcition damper that possesses main body cover 20 and axis body 30.This frcition damper, the inner peripheral surface that contacts main body cover for the outer peripheral surface that makes axis body is provided with main body cover and axis body, on any of this inner peripheral surface and outer peripheral surface, in order only to make its part contact the opposing party a plurality of recesses are set, strive for making the braking force of relative main body cover rotation stable thus.
In the rotation damper that above-mentioned open communique is recorded and narrated, there is following problem.
(1) owing to only is provided with contacting part merely, so can not make it to have the damping and amortization that the directivity when rotating because of main body cover is brought.
(2) try hard to reduce the area of contact of main body cover inner peripheral surface and axis body outer peripheral surface to strive for stablizing braking force owing to only recess is set, so damping force is adjusted in the increase and decrease of area that can only be by contacting part, the damping force of its damper is determined when therefore assembling, and can not adjust during use.
Summary of the invention
Purpose of the present invention is to solve above-mentioned prior art problems, is to provide installation simple in structure good, in light weight, can make at an easy rate in addition,, can make damper device that damping and amortization changes significantly, the damping and amortization excellence simultaneously according to relative differential direction.Particularly in providing, the space that does not need allowable strain in the large deformation side, can also make axially compact and weight reduction, and then, even small amplitude also can be followed small amplitude and be moved, can bring into play the damper device of damping and amortization, in addition, when can bring into play the differential damping and amortization of rotation effectively, also can adjust the damper device of its damping and amortization arbitrarily.
The constitutive characteristic of damper device of the present invention is, form with the flange plate member by casing and the braking that is configured in this casing, this flange plate member, at least leaving the part at its center is made by elastomer, and to axial or phase countershaft radiation direction tilt and form, and the circumferential surface of flange plate member has the tilt angle for the internal face of casing and contacts.Like this, just can provide installation simple in structure good, in light weight, can make at an easy rate in addition,, can make damper device that damping and amortization changes significantly, that have advantageous feature simultaneously according to relative differential direction.
The damper device that first example of the present invention is relevant, it is the straight line moving type damper device, its formation is characterised in that, possess casing, in this casing the pistons reciprocating bar, be installed in the braking flange plate member of making by elastomer on this piston rod, this flange plate member, on its corresponding both faces, be coupled with cone towards periphery, and the internal face of the circumferential surface of flange plate member contact casing.
For this reason, this straight line moving type damper device, when static, the internal face of casing and as the circumferential surface crimping of flange plate member end face is to close by some crimping preferably.Therefore, the flange plate member preferably has can become the external diameter that the such size of state is closed by this system.
Above-mentioned flange plate member is characterised in that the part of leaving its center is formed the tilted shape of a direction.
In above-mentioned straight line moving type damper device, the flange plate member, for piston rod in casing when static to as the A direction motion of an axial end time, make the circumferential surface and the cabinet wall face of this flange plate member, the tying by the frictional force of the relative cabinet wall face of flange plate member circumferential surface, make motion tying, and produce damping, and be installed on the piston rod to the A direction.Utilize moving of piston rod, the circumferential surface of flange plate member further is pressed in the cabinet wall face, because crimp force improves, so produce bigger frictional force, the result can carry out damping effectively.Here, so-called A direction is meant that for example piston rod moves the retracted orientation that causes.
In addition, above-mentioned flange plate member, for piston rod in casing when static to the time as the opposite B direction motion of the A direction of an axial end, make this flange plate deflection, do not produce crimp force (preferably producing hardly), and in order not produce friction and then damping (preferably hardly produce), and be installed on the piston rod.

Embodiment
Below, describe with reference to the accompanying drawing straight line moving type damping device example that just the present invention's first example is relevant.
Fig. 1 is the constructed profile map of straight line moving type damper device of the present invention, and shown in Figure 2 is the sectional drawing of the employed flange plate member of this damper device, and also having shown in Fig. 3 is for the phase diagram of this damper device work is described.
As shown in Figure 1, this damper device, in straight line moving type damper device 101, possess columnar casing 102, in casing pistons reciprocating bar 103, as disk shape braking flange plate member 104 with member.This flange plate member has the bigger external diameter in footpath of interior week than assembled casing under free state.And on the part corresponding both faces of leaving this flange plate member center, on a direction, added cone towards periphery.The peripheral side of flange plate member 104 and the internal face of casing are to close by some crimping.Symbol 105 among the figure is conical sections of flange plate member 104.
In casing 102, an axial end is a closed end 106, and the other end is open end 107.This open end 107 uses the pad 107a that is made by well-known rigid plastics such as fluorocarbon resins airtight.In addition, effluent hole 108 is set near the closed end 106, when closed end 106 side spaces were compressed because of moving of piston rod 103, the air in this space can be to outside dissipation in the casing.And then, also can valve member 109 be set near closed end 106, apply the braking that brings by flange plate member 104 thus to carry out air damping.
Have again, on the friction slip face of above-mentioned flange plate member 104 and casing 106, also can be coated with oiling agent.This oiling agent can use oiling agent that has for example mixed molybdenum disulfide in the fluorine resin base lubricant etc.By using this oiling agent, can adjust, with the abrasion of inhibition flange plate member 104, and can moderately bring into play frictional force.
In addition,, for example can use in use and ooze out from basic rubber as rubber, and the self lubricity rubber that adds oiling agent (hereinafter referred to as exudative oiling agent) to cooperate with basic rubber in the outside movable of giving lubricity and form.
The employed flange plate member 104 of damper device among Fig. 1, as Fig. 2 (a) and (b), if having the conical section 105 that favours a direction, its shape is not particularly limited so.About the various variation of flange plate member, narration in the back.
During the work of above-mentioned damper device, the circumferential surface of cabinet wall face and flange plate member be to close (contact) state, be in the relation shown in Fig. 3 (a)～(c).
Shown in Fig. 3 (a), when static, the internal face of casing 301 and be to close by some crimping as the peripheral side 303a of flange plate member 302 end faces.For this reason, damper device when assembling, for the peripheral side of the internal face that becomes casing 301 and flange plate member 302 by the state of some crimping, have the flange plate member of conical section 303, its diameter is larger than the interior Zhou Jing of casing.In the figure, symbol 304 expression piston rods.
When static during setting in motion, when the A direction shown in Fig. 3 (b) is moved (during contraction), have the peripheral side 303a of flange plate member 302 of conical section and the internal face of casing 301, rely on the frictional force of the relative cabinet wall face of flange plate member peripheral side and tying, motion is by tying.Because moving of piston rod 304, the peripheral side 303a of flange plate member rises to the position with conical section flange plate member body position equal extent in addition.Along with the rising of this peripheral side 303a, produce towards flange plate member 302 repulsion radially, and further flange plate member peripheral side is pressed in the internal face of casing 301, thus produce bigger frictional force, and then can carry out damping effectively.
In addition, when the B direction shown in Fig. 3 (c) is done exercises (during elongation), because the flange plate member 302 with conical section 303 easily to its cone direction deflection, so produce crimp force hardly, rubs and then damping thereby produce hardly.
Straight line moving type damper device of the present invention, as mentioned above, preferably the part of leaving flange plate member center is formed the tilted shape of a direction, utilize the rigidity difference that causes because of its shape thus again, change damping force in the piston rod to-and-fro motion, the generating mechanism of damping force is different with above-mentioned announcement communique (the flat 11-5112269 of special table).In the prior art, when needing supporting plate, the crimp force when static is the highest, to this in the present invention, does not use this supporting plate, and piston rod crimp force when a side moves than when the opposing party moves is high.Have, crimp force is high again, and friction becomes big certainly, and it is big that damping also becomes.As mentioned above, braking force very big different damper device of the present invention on shrinkage direction and prolonging direction can be used for various uses in every field.In addition, as above-mentioned flange plate member 302, if corresponding face is made the cone with same tilt, even so owing to when majority is overlapping, also can shorten axial length, so can make compact damper device, thereby can be used for multiple use.
In straight line moving type damper device of the present invention, both can the sleeve of the flange plate member with conical section in embedding piston rod be installed, also can directly not embed in the piston rod and install between sleeve.For the situation of not using sleeve, if under the axial pressure state mounting flange member, so because because of elastomeric distortion hole enlargement, thus the crimp force of cabinet wall face is risen, thereby can change frictional force and then damping force.In addition, by additional long-range mechanism, can also regulate from the outside after the assembling.As an example of this long-range mechanism, have from outside the flange plate member is compressed in axial mechanism.By this mechanism is set, can regulate the crimp force with outer barrel member, i.e. damping force.
The shape that can be used for the flange plate member of straight line moving type damper device of the present invention, as mentioned above, so long as added the flange plate member of cone, then be not particularly limited, the sectional drawing of the various variation that its flange plate member is desirable is shown in Fig. 4 (a)～(g).In these figure, the conical section of symbol 401 expression casings, 402 expression flange plate members, 403 display plates, 404 expression sleeves.
Shown in Fig. 4 (a) is that the cone that is added on the flange plate member corresponding both faces is different with the situation with same tilt angle shown in Figure 2, has the flange plate member of the different conical section 402 of each face cone body angle; Shown in Fig. 4 (b) is to have to have added the flange plate member of conical section 402 of holding the cone of regulation curvature at each face; Shown in Fig. 4 (c) be on flange plate member front end corresponding both faces, added cone in, on its conical section 402, have the flange plate member of an otch (breach) at least; Shown in Fig. 4 (d) is one-piece type flange plate member; Shown in Fig. 4 (e) is to be mounted under the multi-disc flange plate member shown in Figure 2 that has added cone on the flange plate member corresponding both faces is being separated by state at interval, on the position beyond the conical section between each flange plate member 402, be inserted into the plate of making by rigid plastics etc. 403, the preferably state that is fixedly secured as pad; Shown in Fig. 4 (f) is the flange plate member that is installed in the state on the piston rod between sleeve 404; Shown in the figure (g) is the flange plate member that has added cone on flange plate member corresponding both faces, wherein is provided with the joint-cutting (cutting into) of regulation shape on its conical section 402.Shown in Fig. 4 (e), when using pad, the external diameter of pad need be made as the size that can not limit the flange plate distortion according to glide direction.In addition, the joint-cutting of the otch of above-mentioned Fig. 4 (c) and Fig. 4 (g) when making with lubricator to slip surface, can also stockpile groove as oiling agent and play a role.
Moreover the internal face system of the peripheral side of above-mentioned flange plate member and casing 401 closes.
Straight line moving type damper device of the present invention, as mentioned above, a relative side's shrinkage direction constitutes than the big damping and amortization of the opposing party's prolonging direction to produce.This damping and amortization, because of flange plate member number, thickness and material, the tapering of the conical section of flange plate member and shape, and beyond flange plate member conical section and its part ratio etc. and change arbitrarily.Therefore, be complementary by kind and select and to design these parameters aptly, just can provide desirable damper device with the industry machine of suitable damper device.
Then, as follows, make the test sample of straight line moving type damper device of the present invention, this test is assemblied on the omnipotent vibration tester with sample, measure the Load-displacement Characteristics of Ram when making the sample to-and-fro motion with certain vibration velocity.
Use the natural rubber material, sulfidization molding is that external diameter 26.3mm, thickness 3mm, cone start point distance center 10mm and cone angle are 35 ° band cone disk shape, has made the have rubber hardness A65/S flange plate member of (JIS K6253A type duroscope).For 3 these flange plate members, the pad of interaction cascading external diameter 20mm, thickness 0.8mm, and after being assemblied on the piston rod front end with nut, the oiling agent that has mixed molybdenum disulfide in the fluorine resin base lubricant is coated in the sliding position of above-mentioned flange plate member, and intercalation assembles on the tubular casing of internal diameter 25.8mm, it as the test sample.This test is assemblied on the omnipotent vibration tester with sample, at room temperature, moves back and forth, measured Load-displacement Characteristics of Ram at this moment with 2Hz ± 20mm.Its result as shown in Figure 5.
As shown in Figure 5, straight line moving type damper device of the present invention, B direction slip (direction that damping is little) is compared with A direction (direction that damping is big), has represented the poor of about 5 times damping force.
By above-mentioned test as can be known with sample, though stacked pad, but,, produced the true directivity of the system of Himdu logic and the damping force that causes is poor so can be not that the blue dish of lambda limiting process deformation of members plays a role according to glide direction because the pad external diameter is littler than the external diameter of flange plate member.
Below, for above-mentioned test sample, use 13 flange plate members interaction cascading pad similarly, and then the insertion spring constant is the helical spring of 6.6N/mm (0.67kgf/mm) between the bottom of piston rod front end and tubular casing, make test and use sample, this test is assemblied on the omnipotent vibration tester with sample, vibration frequency is changed into 0.1Hz, 0.2Hz, 1Hz, 2Hz, 4Hz, measure Load-displacement Characteristics of Ram separately, its result as shown in Figure 6.
As shown in Figure 6, straight line moving type damper device of the present invention, relevant A direction is slided, and load uprises corresponding to vibration velocity, has speed dependence.To this, relevant B direction is slided, and does not almost find differences.
Therefore, recognize to have in the difference of tangible damping characteristic in to-and-fro motion, also have relevant load (impact load) fast, will produce big damping force, relevant load at a slow speed will produce the characteristic of little damping force.
Above-mentioned characteristic is the damper device Ideal Characteristics as suspension etc.
Below, be elaborated with regard to the relevant rotary type damper device example of second example of the present invention with reference to accompanying drawing.
Fig. 7 is the schematic isometric of the braking of employed disk shape in rotary type damper device of the present invention with the flange plate member, Fig. 8 and Fig. 9 are respectively for schematic cross-sectional side view (Fig. 8 (a) of the rotary type damper device formation that the present invention is correlated with is described, Fig. 9 (a)) and A-A sectional drawing (Fig. 8 (b), Fig. 9 (b)), Figure 10 is the drawing in side sectional elevation of expression rotary type damper device of the present invention employed flange plate member different shape, Figure 11 be with cabinet wall face state of contact under the schematic representation of protuberance different shape example of the employed flange plate member of expression rotary type damper device of the present invention.
As shown in Figure 7, flange plate member 501, by have be configured on its axle center be the portion of closing 502 be to close member 503 to form.This is that the outer peripheral surface that closes member possesses protuberance 504, and the radiation direction of this protuberance phase countershaft tilts and forms.
In Fig. 7, flange plate member 501 is to utilize system to close the example that material of the same race that member and protuberance two members are made by elastomers such as rubber, man made rubber forms.Member closes in system and protuberance both can be formed by material of the same race, also can be formed by different materials.In addition, also can close member being and protuberance forms respectively, fixing.Also can be, this be to close member by making such as metal, plastics, rubber and man made rubber, and protuberance is made by elastomers such as rubber, man made rubber.This rubber for example can comprise and oozing out from basic rubber in use, and the exudative oiling agent of giving lubricity is cooperated with basic rubber and the self lubricity rubber formed.
Here, the self lubricity rubber that just can be used for damper device of the present invention describes.
As the basic rubber of self lubricity rubber, though the preferably rubber (for example nitrile butadiene rubber etc.) or their mixed rubber of the rubber of shock resistance excellence (for example natural rubber etc.), wear resistance performance excellence are not particularly limited.Can give an example natural rubber, nitrile butadiene rubber, hydrogenation nitrile butadiene rubber, propylene diene binary polymerization body rubber, various fluorine rubber, the acrylic rubber etc. of containing, but can be according to purposes (specification) and described later and the natural disposition mutually of exudative oiling agent suit selection and mixing.And, as exudative oiling agent, as long as provide self-lubricating function to basic rubber, the words of proving effective in the use, then be not particularly limited, can enumerate the fatty acid of the wax class of various oils, paraffin wax etc. of silicone oil and rotten silicone oil etc. and fatty acid and soap, aliphatic amide etc.In the above description,, do not limit rubber though be to be example with rubber, also can be in satisfying the scope of function with suitable man made rubber as the basis.
As a concrete example of this self lubricity rubber, preferably at basic rubber 100 unit of weights, make exudative oiling agent be made as from 1.5 unit of weights to 10 unit of weights about.Use level less than 1.5 unit of weights for not obtaining the tendency of abundant seepage discharge, surpass 10 unit of weights during use, and seepage discharge is excessive easily, and in addition, processability is significantly reduced tendency.Seepage discharge is excessive, owing to be difficult to obtain necessary moment of torsion, and exudative oiling agent is exhausted in advance easily, so need select suitable use level according to purposes.
In addition, above-mentioned basic rubber for example can cooperate vulcanzing agent, vulcanizing accelerator, vulcanization aid, processing aid, strengthening agent, tenderer, antiager aptly, bondingly give agent etc. and modulate.As vulcanzing agent, can for example use sulphur, organic peroxide, oxime, alkyl phenol resin, disulfide, metallic oxide, polyamide-based etc. aptly according to the rubber kind.As with the vulcanizing accelerator of vulcanzing agent combination, can be from sulfanilamide (SN) usually, selection a kind or 2 kinds of uses the thiazole system, the waste acyl of two hydroxylamines system, dithiocarbamates, xanthic acid salt, thiocarbamide etc.As vulcanization aid, can use zine oxide usually.As processing aid, can use the fatty acid and the derivative of fatty acid class of stearic acid etc.In addition, as strengthening agent, can use carbon black, silica etc. suitably usually.As tenderer, can use the process oil of paraffin series, naphthene series, fragrant family etc.As antiager, bondingly give agent etc., can use well-known material.
In self lubricity damper rubber used in the present invention, as above-mentioned exudative oiling agent, preferably use the aliphatic amide, that for example selects from stearylamine, palmitin acid amides, oleyl amine, savoy amine (ェ Le シ Le ァ ミ De), lauryl amine etc. at least is a kind of.Like this and since by exudative oiling agent as the aliphatic amide, can stablize and be oozed out, so can the long term maintenance self lubricity.
As Fig. 8 (a) and (b), rotary type damper device 601 of the present invention, possess columnar casing 602, rotatably be configured in axis body 603 in this casing, as being installed in disk shape braking on this axis body with the flange plate member 604 of member.In the figure, though the flange plate member is installed on the axis body with the state that is fixed on the sleeve 605, can not be installed on the axis body between sleeve yet.When sleeve, the concavo-convex (not shown) of the concavo-convex and axis body of the internal diameter shape of this sleeve is chimeric, and axis body and flange plate member (sleeve) can rotate together.But when hope can constitute sleeve and axis body with decomposing, the size of handy Spielpassung was carried out chimeric.
This sleeve 605 for example has by sulfuration and is bonded on the flange plate member 604 that the rubber of its outside is made, by the chimeric matrix part that is fixed on the flange plate member on the axis body 603.Sleeve is a disc-shape, and the center is provided with and the chimeric fixing embedding part of axis body, but its internal diameter shape is not particularly limited, also can sleeve and axis body is chimeric and axis body and flange plate member can rotate together and constitute.For example, preferably being with keyway shape, gear shape, two face widths, polygon (for example quadrangle, pentagon, hexagon etc.), also can be the shape of spline etc.At this moment, the outer circumferential face shape of axis body constitutes to be suitable for this sleeve diameter shape.Have, this is chimeric again, when not needing to decompose sleeve and axis body, also can be drive fit etc.
As mentioned above, not necessarily need sleeve 605, also can be according to payload, flange plate member 604 still is that sleeve is all made by elastomer.
As mentioned above, the protuberance of contact casing 602 internal faces (for example, the plumage portion of rubber system) 604a, owing to the relative radiation direction of axis body 603 tilts to form, so for the flange plate member 604 that rotates for following the axis body rotation, during along direction casing relative rotate opposite with the radiation direction (true dip direction) of protuberance, utilize the rotational resistance (frictional force) that produces between the fore end outer circumference face 604b of protuberance and the cabinet wall face, the protuberance opposing is withstood at the cabinet wall face, so produce damping due to rotation between flange plate member and casing.At this moment, on protuberance,,, can utilize the existence of oiling agent to suppress abrasion so, also can obtain suitable frictional force even oiling agent as described below is clipped between protuberance and the cabinet wall face because power is applied to the protuberance compression direction from the cabinet wall face of crimping.
On the other hand, for the flange plate member 604 that rotates for following axis body 603 rotations, along with the radiation direction equidirectional casing 602 relative rotations of protuberance 604a the time, because the fore end outer circumference face 604b of protuberance does not resist the cabinet wall face, rather be that protuberance collapses corresponding to rotation, so between this front end outer circumferential face and cabinet wall face, be difficult to produce rotational resistance, produce damping due to rotation between flange plate member and the casing hardly.
Therefore, rotary type damper device of the present invention can at random make damping due to rotation power have difference according to sense of rotation, and it is had many uses too.
Casing 602 also can rotatably dispose flange plate member 604 (axis body 603) therein, and promptly axially two ends are to discharge end, can an end be closed ends also, and perhaps two ends all are closed ends.During for closed end, axis body can use the pad for example made by well-known rigid plastics such as fluorocarbon resins etc. to install on the sidewall of casing, and is sealed in the casing.But the rotary type damper device that the present invention is correlated with is compared with fluid-tight type etc., adopts easy airtight just enoughly, does not get final product so long as do not invade big rubbish, dust, water etc.
On the friction slip face of the internal face of the front end outer circumferential face 604b of protuberance 604a and casing 602, also can be coated with oiling agent.As oiling agent, can be according to suitable oiling agents of suitable employing such as the endurance strength of the material of protuberance, design, loads.By using this oiling agent, owing to can adjust suppressing the particularly abrasion of protuberance of flange plate member, and can moderately bring into play frictional force, so durability also will improve more.
Be fixed on the flange plate member 604 on the sleeve 605, as shown in Figure 8, for example, the direction of alignment protuberance incline section 604c, 3 are overlapping, connect to insert to have with the axis body 603 of the matched outer peripheral surface of above-mentioned sleeve diameter shape to install, by connections such as bolts, and be fixed on the axis body.In this example, in order to illustrate, though represented 3 examples that the flange plate member is overlapping, its sheet number is not particularly limited, and according to hope, both can be made as 1, also can be made as the multi-disc more than 2.
As mentioned above, with regard to Fig. 8, the installation of flange plate member 604, both can between, also can be not between sleeve 605, the flange plate member material of protuberance 604a at least can be the sort of man made rubber such as well-known synthetic rubber and elastomeric plastics both, much less also can be natural rubber.
Above-mentioned flange plate member 604, as shown in Figure 7, for example at its outer peripheral surface, though radiation direction that can the phase countershaft, form and be provided with and tilt and formation projection (protuberance), if but can reach desired purpose, its protuberance shape and formation method are not particularly limited so.About the various variation of flange plate member, will narrate in the back with protuberance.
In addition, as Fig. 9 (a) and (b), in rotary type damper device 701 of the present invention, identical as the casing 702 of its constituting component, axis body 703, sleeve 705 etc. with Fig. 8 situation, but the braking of disk shape is different with the shape of flange plate member 704.When constituting, (for example, the plumage portion of rubber system) fore-end is provided with and favours axial cone part 704c the fore end outer circumference face 704b of this flange plate member protuberance 604a at its protuberance being touched the cabinet wall face.At this moment, can cause damping error because of the difference of linear movement direction (left and right directions among Fig. 9 (a)).
In addition, though not expression among the figure, but, have the axis body of making and possess the compressive force regulating mechanism, the damper device that the braking in being set at casing constitutes with adding axial compressive force on the flange plate member as the present invention and then the relevant rotary type damper device of other examples.At this moment, owing to can clamping in the axial pressure power of contracting to the flange plate member, institute so that the flange plate member be out of shape at circumferencial direction, thereby after the damper device assembling, also can adjust damping force.As this flange plate member, whole flange plate member is suitable for rubber system.
For example, preestablish axial compression mechanism (for example screw thread etc.), in device stops, adjusting the device of this mechanism aptly.At this moment, retention mechanisms such as screw thread are set on axis body merely, casing is unfixing.In addition, also this axial compression mechanism of handlebar (for example screw thread etc.) is set on the casing fastened setting the when becoming big by the differential angle with casing, the device that damping force is changed because of angle dependence.At this moment, for example the screw section is set, the screw thread that cutting in advance cooperates with movable axis body in the casing side.
Below the present invention is correlated with the work of rotary type damper device the time, the front end periphery of cabinet wall face and flange plate member protuberance be to close state to study.
Above-mentioned rotary type damper device 601,701, when static, for fore end outer circumference face 604b, the 704b of protuberance 604a, the 704a of the internal face that makes casing 602,702 and flange plate member 604,704 becomes by some crimping and is that the state that closes is assembled, so have the external diameter of flange plate member of the protuberance of inclination, be slightly larger than the internal diameter of casing.
In the rotary type damper device shown in Fig. 8 and 9 601,701, along with the radiation side of the protuberance 604a, the 704a that are formed slopely in the opposite direction during upper box 602,702 relative rotations, utilize front end outer circumferential face 604b, the 704b of protuberance and the rotational resistance between the cabinet wall face, the protuberance opposing is withstood at the cabinet wall face, generation is towards the repulsion radially of protuberance, further protuberance front end outer circumferential face is pressed to the internal face of casing, so produce bigger rotational resistance, produce damping due to rotation between flange plate member and the casing.On the other hand, along with relative rotation of radiation direction equidirectional casing of the protuberance that is formed slopely the time, because the front end outer circumferential face of protuberance is not resisted the cabinet wall face, rather be that protuberance is corresponding to rotation and deflection, collapse to sense of rotation, so be difficult to produce rotational resistance, produce damping due to rotation between flange plate member and the casing hardly.
Because of the very big different rotary type damper device of the present invention of sense of rotation braking force, as mentioned above, can be applied to various uses in every field.In addition, shown in above-mentioned flange plate member, correspondingly look like fruit and have the cone of same tilt,, thereby can make the damper device of compactness, so and then can be used for multiple use even also can shorten axial length during overlapping uses of multi-disc.
In rotary type damper device of the present invention, as mentioned above, both can be installed in flange plate member on the axis body between sleeve with protuberance, can not be directly installed on the axis body between sleeve yet.For the situation of not using sleeve, if under the state of axial pressure the mounting flange member, owing to utilize the distortion hole enlargement of elastomer etc., the crimp force of pressing to the cabinet wall face rises, so can change frictional force and then damping due to rotation power so.In addition, in the seating means of flange plate member and axis body, when only having constituted the flange plate member, can comprise that also direct sulfuration is bonded on the means on the axis body by rubber.And then, by additional long-range mechanism, can also regulate from the outside after the assembling.In an example of this long-range mechanism, have from aforesaid outside the flange plate member is compressed in axial mechanism.By this mechanism is set, can regulate the crimp force with outer barrel member, i.e. damping force.
The flange plate member that can be used for rotary type damper device of the present invention as mentioned above, so long as have the flange plate member of the protuberance that is formed slopely, then is not particularly limited.The desirable various variation of this flange plate member are shown in Figure 10 (a)～(d).
Shown in Figure 10 (a) is the radiation direction of phase countershaft, possesses the disk shape braking flange plate member 804 of the protuberance 804a (representing its front end outer circumferential face with 804b) that is formed slopely.This flange plate member is around sleeve (being to close member) 805 is fixed on the axis body of metal or resin system etc., and to be its protuberance thickness thinner than segment thickness beyond the protuberance and the band step type that constitutes.The so-called band step type of being somebody's turn to do when being installed in a plurality of flange plate members on the axis body exactly, being provided with the gap and constituting between axially adjacent each protuberance (for example rubber system plumage portion).By reserving the gap, the distortion capacity of compressed protuberance in the time of can absorbing protuberance and withstand casing.By the suitable tilt angle of the relative rotor shaft direction of protuberance, the height of protuberance set, can adjust the moment of torsion of generation.In addition, sleeve be the internal diameter shape of closing the 805a of portion, for example have with above-mentioned shapes such as keyway shape, gear shape, hexagonal configurations, on the other hand, the external surface shape of axis body, having to be to close the chimeric shape of portion's shape with this.At this moment, both can be between flange plate member and the axis body between sleeve, also can be not between sleeve.
Shown in Figure 10 (b) be have with the braking of the disk shape of the similar face shaping of Figure 10 (a) situation with flange plate member 804.This flange plate member is except being beyond the rubber system flange plate member of the thickness of the protuberance 804a band step type thinner and integrally formed than segment thickness the protuberance, and is identical with the situation of Figure 10 (a).
Shown in Figure 10 (c) is disk shape braking with other variation of flange plate member.Be that the thickness of the rubber system protuberance 804a of the flange plate member 804 on the axis body that is fixed on metal or resin system etc. between sleeve 805 is set as identical type with protuberance part in addition.Being installed in of flange plate member clips liner and carries out between the flange plate member.By mutual configuration flange plate member and liner, can between the flange plate member of adjacency, the gap be set between protuberance promptly.The shape of flange plate member has and simple this advantage of comparing of other.Also can all make rubber system to the flange plate member.About other aspects, identical with the situation of Figure 10 (a).
Shown in Figure 10 (d) is to have the flange plate member 804 that is provided with the protuberance 804a of axial cone part at fore-end.This flange plate member is to be fixed on flange plate member with the level on the axis body of metal or resin system etc. between sleeve 805.Use this flange plate member, particularly can also cause damping error the difference of linear movement direction.About other aspects, identical with the situation of Figure 10 (a).
Other shape has the shape of the flange plate member of protuberance, is not restricted to above-mentioned shape, even as long as can reach purpose of the present invention, also can be used.
In addition, when a plurality of flange plate component compositions were used, both only combination had identical shapedly, also can make up different shapes.For example, in rotary type damper device shown in Figure 8, can make up the different flange plate member of the true dip direction of protuberance and angle of inclination.For example, the flange plate member with the different protuberance of true dip direction is made up, the flange plate member of rotation and the relative rotation between the casing for following axis body rotation can just changeed/individually adjust damping force according to hope on the reverse direction.This is when being used for the suspension of bicycle etc., owing to can adjust extending side and compressed side, so very suitable.
In addition, also can use to have the true dip direction part, at this moment, utilize the ratio of different true dip directions, produce the sense of rotation damping error for the flange plate member that rightabout protuberance constitutes.This is useful when the damping due to rotation that positive veer and reverse direction all need to wish.
And then, the flange plate member that possesses the bigger protuberance in angle of inclination is made up, can obtain bigger damping due to rotation power with the less flange plate member of sheet number.At this moment, damper device is comparatively compact.
As mentioned above, damping due to rotation power can be adjusted by use sheet number, protuberance true dip direction and the angle of inclination etc. of flange plate member, in addition, if possess above-mentioned compressive force regulating mechanism, also can adjust damping force aptly after the assembling of damper mechanism.
The protuberance of flange plate member can also be the shape shown in Figure 11 (a)～(g) in addition.In Figure 11, expression be the state of internal face of the front end outer circumferential face contact casing of protuberance.This Figure 11 (a)～(g) is corresponding with Fig. 4 (a)～(g).
Shown in Figure 11 (a) is the protuberance with the different conical section 902a of cone angle on protuberance 902 corresponding both faces that are added in the flange plate member of casing 901 internal faces contacts; Shown in Figure 11 (b) is to have to have added the protuberance 902 of conical section 902a of holding the cone of regulation curvature at each face; Shown in Figure 11 (c) be on flange plate member front end corresponding both faces, added cone in, on its conical section 902a, have the protuberance 902 of an otch (breach) at least; Shown in Figure 11 (d) is the one-piece type protuberance 902 with a plurality of conical section 902a; Shown in Figure 11 (e) is to be mounted under the multi-disc protuberance that has added cone on the corresponding both faces is being separated by state at interval, insert the plate of making by rigid plastics etc. 903 as pad on the position beyond the conical section 902a between each protuberance, and the state that is fixedly secured; Shown in Figure 11 (f) is to be installed in protuberance 902 state, that have conical section 902a on the axis body between sleeve 904; Shown in Figure 11 (g) is the protuberance 902 that has added cone on corresponding both faces, wherein is provided with the joint-cutting (cutting into) of regulation shape on its conical section 902a.When using the pad shown in Figure 11 (e), the external diameter of pad need be made as the size that can not limit convex part deformation according to glide direction.In addition, the joint-cutting of the otch of above-mentioned Figure 11 (c) and Figure 11 (g) when making with lubricator to slip surface, can also stockpile groove and plays a role as oiling agent.
Rotary type damper device of the present invention as mentioned above, following axis body rotation in the flange plate member and the relative rotation between the casing of rotation, produces damping due to rotation between the two and constitutes for making.This damping and amortization, because of flange plate member number, thickness and material, the cone angle and the shape of the protuberance of flange plate member, and the ratio of flange plate member protuberance and other parts etc. and changing arbitrarily.Therefore, be complementary by kind and select and to design these parameters aptly, just can provide desirable damper device with the industry machine of suitable damper device.
Then, make the test sample of rotary type damper device shown in Figure 12, this test is assemblied on the torsional vibration testing machine with sample, the moment of torsion-torsional amplitudes kinetic characteristic when mensuration rotatablely moves sample with certain vibration frequency.Figure 12 (a) is the cross sectional side view of explanation damper device inside, and Figure 12 (b) is its A-A sectional drawing.
As shown in figure 12, use the natural rubber material, sulfidization molding is the thickness of flange plate member external diameter: 26.6mm (during free length), flange plate member thickness: 5mm (during free length), flange plate member cone part (protuberance): 3mm (during free length), cone start position (during free length): rotary middle spindle 10mm, cone angle (during free length): 30 ° band cone disk shape, made the have rubber hardness A65/S flange plate member 1 of (JIS K6253A type duroscope).4 these flange plate members are assemblied on the axis body 2, and with behind the nut 3 connection axis body front ends, the oiling agent that has mixed molybdenum disulfide in the fluorine resin base lubricant is coated in the sliding position of above-mentioned flange plate member, and intercalation assembles on the tubular casing 4 of internal diameter 25.8mm, it as the test sample.This test is assemblied on the torsion testing machine with sample, and torsional amplitudes is ± 40 °, Test frequency is changed into 0.05/0.10/0.20/0.50/1.00/1.50/2.00Hz rotate, and has measured moment of torsion separately-torsional amplitudes characteristic.Its result as shown in figure 13.
In Figure 13, symbol a, b, c, d, e, f and g represent moment of torsion-torsional amplitudes characteristic of measuring when Test frequency is 0.05Hz, 0.10Hz, 0.20Hz, 0.50Hz, 1.00Hz, 1.50Hz, 2.00Hz respectively.
As shown in Figure 13, rotary type damper device of the present invention, when reversing to-and-fro motion with ± 40 ° of torsional amplitudes, when just changeing (the directions X rotation of high moment of torsion sideway swivel: Figure 12), to produce the higher moment of torsion of 1.0～3.2Nm according to angular velocity (Test frequency), to this, when reversing (the Y direction rotation of low moment of torsion sideway swivel: Figure 12), though more or less change according to angular velocity (Test frequency), but only produce the moment of torsion of-0.51～1.0Nm, not only moment of torsion is little, and its amplitude of variation is also little.That is to say that when having just contrary bigger torque differences, only changing one's position in dextrorotation exists the angular velocity of rotation dependence.
This specific character, for rotating parts such as axle particularly angle of swing be no more than 360 °, and reciprocating industry is more satisfactory characteristic with the rotary type damper device that machine utilized.Much less, can also utilize link mechanism and after for example rack pinion etc. is transformed to the straight line motion of oscillating body to rotatablely move, use, and not be limited to rotation purposes below 360 ° as the damper device of rotating machinery.
